41 * upper/lower-casing and string comparison in code point order.
43 * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
44 * UTF-16 encodes each Unicode code point with either one or two UChar code units.
49 * Some APIs accept a 32-bit UChar32 value for a single code point.
53 * Code-point-related functions treat unpaired surrogates as surrogate code points,
57 * it is much more efficient even for random access because the code unit values
59 * This means that it is easy to determine character (code point) boundaries from
64 * (which use pairs of lead/trail code units called "surrogates"),
66 * a single UChar code unit (i.e., their code point values are <=0xffff).
